Description
Technical Field
The utility model relates to a ventilation unit of plant especially relates to a beasts and birds house with ventilation device.
Background
Ventilation system is a device commonly used in the livestock and poultry house in the aquaculture, guarantees indoor environment through the foul smell in the continuous discharge livestock and poultry house, and current ventilation system mainly drives the gas flow through the fan drive, and however, the fan can produce certain noise at the in-process of long-time operation to the poultry life of influence breed.
For example, the chinese patent document discloses "a pigsty ventilation device", which is disclosed as CN109122333A and includes a first ventilator and a second ventilator, which has a disadvantage that if a long time ventilation is required, the ventilators need to be continuously started, so that the poultry and livestock are affected by noise for a long time, and the normal growth of the poultry and livestock is not facilitated.
Disclosure of Invention
The utility model relates to an overcome prior art, need keep the long-term ventilation in the animal and poultry house through the fan, lead to can lead to the fact the noise influence to the birds poultry, be unfavorable for the problem of the normal growth of birds poultry, provide an animal and poultry house with ventilation device, need not to also can guarantee the continuous ventilation in the animal and poultry house through the fan drive to make birds poultry can grow better, and accepted the energy.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model discloses, a beasts and birds house with ventilation device, including roof, ground, wall body, install the exhaust tuber pipe on the wall body, still be connected with the exhaust chimney on the exhaust tuber pipe, the exhaust chimney is located and is equipped with the heat-sink shell on the part of roof top.
The part above the roof can absorb heat of the external environment and solar illumination through the heat absorption layer, so that the temperature of the upper part of the exhaust chimney is increased, the gas flow speed of the upper part in the exhaust chimney is accelerated after the temperature is increased, the pressure intensity is reduced, the pressure difference is formed between the upper part and the lower part of the exhaust chimney, the gas at the lower part is discharged out of the exhaust chimney, the gas in the livestock and poultry house is discharged in the mode, a fan does not need to be used for driving for a long time, noise can not be continuously generated, the normal growth of livestock and poultry is protected, and energy is saved.
Preferably, the exhaust air pipe is provided with an upper air suction opening and a lower air suction opening, the upper air suction opening is positioned at the upper part of the wall body, and the lower air suction opening is positioned at the lower part of the wall body or below the ground; because the odor in the livestock and poultry house contains a plurality of components, and the densities of the components are different, the gas in the livestock and poultry house can be layered to a certain degree, the part containing more light gases such as ammonia gas and the like can float on the upper part of the livestock and poultry house, the part containing more gases with higher densities such as hydrogen sulfide and the like can sink on the lower part of the livestock and poultry house, the part with relatively less odor content is positioned in the middle part of the livestock and poultry house, and the part containing more odor in the gas can be preferentially discharged through the upper air suction opening and the lower air suction opening, so that the better ventilation effect is achieved; when the interior of livestock house produces more foul smell because of the excretion of birds, need air exhaust to the foul smell as early as possible, otherwise owing to receive various disturbances, for example the walking of birds in livestock house, can make the gas of density difference mix with higher speed, lead to the foul smell to be difficult to discharge, and because exhaust system continuously operates in this scheme, can guarantee the timely discharge of foul smell, in addition, because the drainage time of birds is mainly concentrated on daytime, and daytime outdoor temperature is higher, the pressure differential that forms in the exhaust chimney is bigger, better exhaust effect has.
Preferably, pipeline air valves are arranged at the upper air suction opening and the lower air suction opening; through pipeline blast gate can control the temporary closure of last inlet scoop or lower inlet scoop, when last inlet scoop temporary closure, the combustion gas uses heavier gas, like hydrogen sulfide for giving first place to, when lower inlet scoop temporary closure, the combustion gas uses lighter gas like ammonia for giving first place to, can control the gaseous main component of exhaust through the switch of upper and lower inlet scoop to the convenience carries out the pertinence to it and handles.
Preferably, the ground is provided with a dung leaking plate, and the lower air suction opening is positioned below the ground; the dropping leaking plate can enable the flowing part in the livestock excrement to leak downwards, so that the relative dryness of the ground in the livestock house is ensured, the content of odor in the downwards leaking part is more, and the odor can be better exhausted by arranging the lower air suction opening below the ground.
Preferably, the exhaust air pipe is further connected with a fan pipe, the fan pipe is provided with an exhaust fan and a fan air valve, the exhaust fan can be used for auxiliary exhaust, when the odor content in the livestock and poultry house is high and needs to be exhausted as soon as possible, the outdoor temperature is insufficient, and under the condition that the pressure difference generated in the exhaust chimney is insufficient, the auxiliary exhaust can be performed by starting the exhaust fan, and the exhaust fan does not need to be started for a long time, so that the influence on livestock and poultry is small.
Preferably, the material of the heat absorption layer is chromium nitrate or nano carbon black, the absorption rate and the light-heat conversion rate of the chromium nitrate and the nano carbon black are high, and the light energy of sunlight can be quickly converted into internal energy of the heat absorption layer, so that a better heat absorption effect is achieved.
Preferably, an air pressure sensor is installed at a connection position of the exhaust air duct and the fan duct, the air pressure sensor can detect air pressure in the exhaust air duct, and the exhaust effect can be judged according to the detected air pressure, so that the exhaust fan is controlled.
Therefore, the utility model discloses following beneficial effect has: (1) continuous ventilation in the livestock and poultry house can be ensured without starting a fan for a long time, continuous noise generation is avoided, and energy is saved; (2) the main components of the discharged gas can be controlled through the pipeline air valve, so that the subsequent treatment of the gas is facilitated; (3) the switch of the exhaust fan can be controlled by judging the exhaust effect, so that auxiliary exhaust is performed.
